Karyotypes and metaphases of selected populations of E. virens analyzed in this study and representing the most important traits of chromosome morphology. (A) Sicily, a sexual female, red arrowheads show chromosomes with satellites, blue arrowhead shows a pair of metacentric chromosomes, yellow arrowhead shows a small metacentric chromosome; (B) E. virens, Sicily, the same sexual female as in (A); (C) E. virens, Valencia, Triops Pond, Spain, an asexual triploid female; (D) E. virens, Normandy, France, an asexual triploid female, yellow arrowhead shows a small disparate metacentric chromosome; (E) E. virens, Spain, San Carlos (Bull Pond), a female of a mixed population, brown arrowhead shows a morphologically distinguishable chromosome; (F) E. virens, France, Normandy, an asexual triploid female; (G) E. virens, Sicily, a diploid sexual female. Chromosome preparations were stained with 4’,6-diamidino-2-phenylindole (DAPI) and inverted. Scale bars indicate 3 µm.
